Very slow printer, though also low-fuss. Appears to be working but I haven't yet taken the time to wait for a print to get all the way through. Not good for very large or very fine prints.

Revision as of 01:37, 17 June 2019

Noisebridge's 3D printing station is one of our Fabrication Resources.

Blue tape is not needed in addition to the buildtak surface, but it doesn't hurt.

TODO:

Install the part cooling shroud and 24v fan - done!

Tighten heat block (mysteriously it's working fine as is)

Install a Bowden cable and attach the wire to it to prevent it from interfering/getting crushed by the gantry.

Install cotton insulator for heat block (upgraded cooler sometimes cools this area too much. Until then, do not run the fan at 100% out it will give you a heater error.

Monoprice Miniprinters

We have a number of Monoprice Select Mini 3D Printers (Mono-4,Mono-3, Ripley). Information on their specifications is found here: https://www.monoprice.com/product?p_id=15365. They key thing to note is they have a 12cm cube of buildable area. [1](MPSelectMini.com) has a wealth of information about them. If you have any problems or successes with the printers please try to log them on their pages if you can.

Turn your STL file into a GCODE file with the MONOPRICE settings before putting the GCODE onto an SD card and putting it into the monoprice printer.

Printing on the Threed

1. Open the Slic3r app

2. In the Slic3r window, click Add...

3. Choose the file you want to print (there is a test file in /Documents/Slic3r/noisebridgelogo2.stl which you can download from Thingiverse)

4. Select the Noisebridge logo file or your own.

5. The file shows up in the preview window. Most of the correct settings are pre-loaded with the configuration file, but if you are using a filament other than PLA, you must change the temperature settings under the "Filament Settings" tab. Check the side of the filament spool for the recommended temperature settings and stick to the low end of the range.

6. Click "Export G-code" to export the g-code file to the SD card (inserted in the computer).

Note: Don't use the path as shown on screen, pick the "F:" drive. Sometimes, the SD-card isn't recognized unless you take out the adapter, insert the SD-card into that and put the whole module in!

7. Remove the SD card from the micro SD card adapter in the Threed computer.

8. Insert SD card gently into a slot on the right side of the 3D printer. You may have to turn the machine off and on again if the SD card is not recognized.

9. Move the knob till it points at "Print" and push it like a button.

9. Turn the knob to choose the file you want to print and push it like a button.

10. If the temperature screen does not say "Preheating" under the extruder side, manually set the preheat temperature by selecting the extruder temp and twisting the knob until the correct temperature is displayed, then push the knob like a button.

11. Watch the progress screen till the temperatures heat up the extruder and platform to the target temperatures (this will take a while so be patient).

12. The printer will start printing.

13. Wait for it to finish and enjoy your finished item by scraping it off the build platform with a thin piece of metal.

14. If the blue masking tape is damaged in the process, remove it and apply some fresh masking tape to the printer surface. Please remember to turn off the printer when you are done printing.

Troubleshooting Monoprice Mini Prints

My print isn't sticking to the bed

Start by replacing the blue painters tape on the print bed. Please don't use Kapton tape for the Monoprice Minis. Kapton tape is expensive and best suited for ABS filaments, which don't print well on the minis.

Next level the bed. If the extruder nozzle is not extruding or tearing up the tape, it is probably too close. If the filament isn't sticking to the bed, it is probably too far. You can use the four screws on the surface of the bed to raise or lower each corner. The bed is level when a sheet of paper can pass between the nozzle and bed at each corner with only slight resistance. You can find the hex keys for leveling the bed in the 3D printing supplies box (a black plastic bin in the fabrication area).

Click Connect to device. (If you have trouble, see Connection Troubleshooting below.)

Connection Troubleshooting

Connection error: The serial port named '/dev/tty.usbmodem1411' could not be found.

It may not be turned on and plugged in.

Printing Troubleshooting

It stops printing midway through.

Are you browsing the Internet memes with Replicator in the background? It can't print very far in the background. Alt-tab/command-tab to bring ReplicatorG to foreground every time it stops and it will resume. This is one of the main reasons to start using the SD card to print: You can use your computer for other things without slowing down or stopping prints.

Printing from an SD card

Put files ending in .gcode on an SD card

Insert SD card into the side-facing slot on the front right side of the case.

PRUSA i3 MK2s PRINTER

Shifted PINDA sensor slightly downwards and ran full XYZ calibration. Got most of the way through but it didn't seem to detect cal point #4 on the second round (smooshed the tip and PINDA sensor into the bed). Working from sections 6.3.5 and 6.3.10.2 in the manual.

M3D Micro

Very slow printer, though also low-fuss. Appears to be working but I haven't yet taken the time to wait for a print to get all the way through. Not good for very large or very fine prints.

Filaments

There are many colors of filament spools to use for printing projects. Take note of which plastic type your filament is and choose settings appropriately. The wrong plastic can damage the printer and make your prints look look like drek.

Note: Replicator defaults are feedrate 40 and 220 degrees C. Setting them to feedrate 80 brings up an accelerated settings warning. The printer is ready to handle 80.
